Tenant Refusing to Pay

[Kaybreh Mathis]

Hello! My husband and I bought an apartment building last month. Apparently, there was a leak roof in a unit that the previous owner was aware of but we were not. After several days of heavy rains, a tenant (who we have already had multiple problems with) sent a message stating that her roof leaked and ruined her bed and clothing. She said she will not pay rent until it is fixed and we reimburse her for the items ruined. Unfortunately, she is currently locked into a lease with 9 more months left. And the lease with the previous owner does not stipulate anything regarding this matter. What do we do? Looking for advice!
